Why Chalk?
Solving large-scale ML problems is a difficult problem that requires mathematical precision and a lot of hard work. Our name is inspired by the favorite tool of mathematicians around the world—the chalkboard. Our logo is taken from the QED symbol, which indicates the end of a mathematical proof.
